This science news story highlights a new initiative by the Hubble Space Telescope to image distant galaxies. The program uses gravitational lenses to image galaxies that are otherwise too distant and faint for the telescope to image. The story...(View More) includes information describing how gravitational lenses are similar to optical lenses. The article also includes a description of parallel fields - a set of observations done in tandem with the gravitational lens observations that will result in six additional HUDF-type observations of the sky. Star Witness News is a series of articles, written for students, that are inspired by Hubble Space Telescope press releases. Supplemental education materials include vocabulary, discussion questions and answers, and identifies relevant Common Core State Standards for English Language Arts.(View Less)

These guides showcase education and public outreach resources from across more than 20 NASA astrophysics missions and programs. The twelve guides - one for each month - contain a science topic, an interpretive story, a sky object to view with...(View More) finding charts, hands-on activities, and connections to NASA science. The guides are modular, so that educators can use the portions that are the most useful for their audiences/events. Following is the theme for each month: January - Betelgeuse, February - Orion Nebula, March - Pleiades, April - Pollux; May - Hubble Deep Field, June - Hercules Cluster, July - Ring Nebula & Veil Nebula, August - The Search for Habitable Worlds, September - Milky Way Galaxy, October - Upsilon Andromedae, November - Andromeda Galaxy, and December - Crab Nebula.(View Less)

This science news story highlights Hubble's infrared image of the Horsehead Nebula. Students will discover why astronomers are interested in this nebula and how they study the nebula using infrared light. Star Witness News is a series of articles,...(View More) written for students, that are inspired by Hubble Space Telescope press releases.

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact...(View More) that even a large, massive planet - such as Saturn - can have low density. They discuss how a planet's density is related to whether it is mainly made up of rock or gas. This activity is part of Explore! Jupiter's Family Secrets, a series designed to engage children in space and planetary science in libraries and informal learning environments.(View Less)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a...(View More) textbook chapter, What Heats the Earth's Interior?, part of the unit, Energy Flow, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.(View Less)

This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or...(View More) wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.(View Less)

This science news story explains the impact of the Hubble Space Telescope over the past two decades. The article describes the telescope, its many servicing missions, the public’s favorite images, the top science findings, and the man for whom the...(View More) telescope is named. Star Witness News is a series of articles, written for students, that are inspired by Hubble Space Telescope press releases. Supplemental education materials include background information, vocabulary, and discussion questions and answers.(View Less)

In this lesson, students explore the cosmic microwave background to understand why it permeates the universe and why it peaks as microwave radiation. Students should be able to explain that the origin of the background radiation is the uniform...(View More) thermal radiation of the big bang and that the radiation produced was evenly distributed around the small early universe, causing it to permeate today's universe. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster.(View Less)

This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing...(View More) sizes stand in for the Sun and the Moon. By moving the balls away from each other, students will determine how far the larger ball needs to be in order to make the two seem similar in size. They will also use the balls to demonstrate a solar eclipse. Lastly, learners will complete a worksheet explaining their findings. This is Activity 12 of a larger resource entitled Eye on the Sky.(View Less)

This is an activity about measurement. Learners will label key points and features on a rectangular equal-area map and measure the distance between pairs of points in order to calculate the actual physical distance on the Sun that the point pairs...(View More) represent. This is Activity 5 of the Space Weather Forecast curriculum.(View Less)
